On Dauphin Island the beach week moves at bike speed. Mornings start on the boardwalk through the Audubon Bird Sanctuary, where the planks cross swamp and dune before the trees open onto the Gulf, and afternoons go to a secluded stretch of sand the town campground's guests mostly have to themselves. By supper everyone pedals back to the rig, salty and sunburned, a short ride from the water.
The island is small and reached by a single causeway, so once the motorhome is level and plugged in, it can sit for the whole stay. Bikes cover everything that matters, from the campground to the sanctuary trails, the public beach, and the ferry landing beside Fort Gaines.
Spring and fall add the migration, when songbirds finishing the long flight across the Gulf drop into the island's maritime forest to rest. On a fallout morning the live oaks in the 164-acre sanctuary fill with warblers you can watch from the 1,000-foot boardwalk and the half-mile loop. Birders plan whole weeks around the weather fronts that bring those mornings.
The town campground beside the sanctuary
The town of Dauphin Island's campground is the pad everyone wants, with the sanctuary next door and its own way to the beach. It has hookup sites, and booking is by phone only and opens a year ahead as of September 2026, so the site is the first reservation and the rig is the second. Ask what length your site takes on that call, then pick the motorhome or trailer to fit it.
Winter regulars and summer families both settle in for long stays, and spring and fall bring birders timing the migration. That means the island's pads, and the family-size rigs to fill them, get booked in every season, so the earlier call wins.
When the town sites are full, Pelican Nest is the private option on the island, across from the public beach with water, sewer, and 30 or 50 amp service on concrete pads. On the mainland side of the causeway, Bay Palms RV Resort in Coden has full hookups and pull-through sites, and it works as a first night if you arrive late or as the week's base when the island is booked.
The Mobile Bay ferry to Fort Morgan, rig and all
The day worth unhooking for is the crossing to the east shore. The ferry runs year-round from SR 193 on the island to SR 180 at Fort Morgan in about 40 minutes, on a longer timetable with a second boat in summer. Taking the motorhome along spares everyone the long drive around the head of the bay.
Fort Gaines stands at the island's ferry landing, worth a morning of its own on another day, and its walls are the last thing you see from the deck as the boat pulls out. The crossing runs between the two Civil War forts at the mouth of Mobile Bay, with Fort Morgan growing on the far shore. Fort Morgan opens onto the Gulf Shores side of the bay, and the big private beach resorts there and in Orange Beach have their own Gulf Shores and Orange Beach pages.
A family-size motorhome needs a phone call before it rolls on, because as of September 2026 the ferry asks anything over 21 feet to call ahead, and boarding is first come, first served with tickets sold only at the landing. For two people traveling light, a smaller rig from the Alabama listings makes the ferry day simpler.
